Khosla Ventures

Check: No Jessy-specific check size is disclosed by Khosla Ventures. Publicly observed work spans an $11 million Spiritus seed financing led by Khosla and Pascal's $8 million seed round, but round size is not the same as the firm's check. Third-party claims of a $100,000–$5 million range were excluded as unverified.

Jessy looks for climate technologies grounded in hard science and non-obvious mechanisms that can make a meaningful dent in greenhouse-gas emissions. Her career shows a materials-to-systems lens: understand the physical mechanism, identify the governing cost and performance variables, build around available supply chains, and prove a path from laboratory result to commercially relevant hardware. Spiritus reflects this in lower-energy, lower-cost direct air capture; Pascal in solid refrigerants operating below 10 bar with off-the-shelf components. She is comfortable with capital-intensive physical products when a technical discontinuity creates a credible route to scale and economics.
